Meow Meow "Voss" Synthesis (4-MMC)

[dnBQByvHb8Zkawbjpx]

Legend!

Now, where do I get HBr in required quantities and concentration in the EU as a casual consumer? Is making it at home the only way? Similarly, how do I get or I purify hydrogen peroxide to 35 % when all I can get is max 10 %?

 

[Dr. MMX]

12% does work too. However remember that in the bromination most important is enolization, its the beggining of the reactiobn. h2o2 can be strange sometimes and it may lead to not react bromine at all enolization occurs in lower temperatures, so if you have the way you can cool a little solution and slowly heat it up later. In every case lower temp is a lot of better for this. Br behavior is precise attack into the correct place where you want it to be, without enolization is a full lose

hi bro can i make 3mmc using this same method by using 3-methylpropiophenone instead of using 4-methylpropiophenone and how to recrstallize can you please explain to me

 

[animeboro]

brown mmc powder is created when we add the acid too quickly and the freebase starts to overheat, then all the pyrizine and other impurities start to come out, which means that we have lower efficiency. the same way we clean the wrong MMC free base, I use water and water with baking soda 3 times and water with baking soda always saves my life even when the entire solution did not react after rinsing with water and baking soda, I get the free base from the green oil of the MMC free base to yellow, changing the color green to blue and then to yellow

 

[William D.]

We can all rush, especially when the product is needed now But we can speed up the process of acidification with compulsory cooling, for example in a pan with cold water.

isorry for my eng, but about topic - cooling the acid and FB is false helping, it help in overall, but not in parts...so what do you have - cooled acid slowly adding to FB, overall temp is low BUT in the surface area of contact of every single droplet - you have nearly boiling temps, you simply just dont see it, so only one solution is - to delute acid with final weight of water, that you plan to crystallize, normally it about 1:3 or 1:5, something like that, in total i get 1g of 4mmc*hbr to 2.5g of water, or more. So bromination can be endede full clean, just rinse the acid, amination....yeah you always need to wash out excess of methilamine, and acidation can be done clean to water

 

[ghostimage]

you can use starter crystall from last batch, you need a clean and big one

Hi
I tried 5 times using exact measurements and steps but never got the whitish precipitation mentioned after adding h2o2. Seems 76ml hbr was not Enough. Would it be better to use 125 ml hbr47 instead of the 76ml mentioned? How long does the precipitaion take as per the above method? Any guesses or advise?

 

[William D.]

You can add an excess of acid now and stir it (so that the process goes faster), but do not add more peroxide.

 

[Tony_Montana]

أنا wash it with water , wich layer i should separate, the gold one or the other one?

 

[Toddler]

to form it takes some time and need continuous stirrer.

 

[NovicechemistEU]

Dude, what proportions of soda and water do you use to remove the excess acid in the proportions you give? I wonder what proportions you use for rinsing, I will make an experiment with your proportions.

 

[ghostimage]

where is no direct answer, first of all you can wash with just water, soda is not good, but if you use it - just take ph papers and watch, it`s about ph, not proportions

@By William D.
@William D. Can I do this by mixing it outside with the lid open?

 

[William D.]

yes, no problem at all. Synthesis with a closed lid is actually dangerous. In this thread, the lid is only used to prevent splashes from spraying out of the bottle

 

[mephedrons]

When we add methylamine 40% in the solution of 2B4M and ethyl acetate, then what should be the range of temperature, and for how long should we stir, and how will we know that the reaction of 2B4M, ethyl acetate and methylamine is complete.

 

[William D.]

to know the exact reaction time, u should use analytical methods such as TLC. But if that’s not possible, u can estimate a reaction time of around 20 mins with heating (exothermic) or forced heating to about 60*C.

 

[Tamishea]

Are you adding a water for Layer separate After 20 min Stirring to RM?

 

[William D.]

Water is used to wash away excess acid from the bromination and to wash away excess methylamine at the end of the second stage.

 

[TheNoob53]

Hey bro, can anyone explain to me what "meow meow" is?

 

[William D.]

4-MMC (Mephedrone)

 

[JASPAL]

hello, at what stage should you rinse with water?

 

[William D.]

the first step is to remove excess acid, and the second step is to remove excess methylamine.

 

[Tony_Montana]

أنا the same problem guys, the uper layer is red , what should i do now, help please

 

[William D.]

heat the mixture with stirring until decolorization

 

[Kodey]

Is there an alternative to HBr? I don't have access to it in my country

 

[William D.]

Is that for the first bromination step or for acidification?
